"I mean jokes aside, I for one would be happy if this game got significant content finally, because it would mean that it wasn't a complete scam / a complete failure, despite all the years that some people no doubt have been frustrated as hell and felt like they wasted their money."
In short, it's probably another scam.
They've been working on this for 4 years, and the game has no content beyond walking and a few dialogues. In the meantime, they've changed game engines, from Unreal Engine to updates for Unity, etc. They come out with updates every 4 years, so they’ll keep resetting engines periodically, and the game may never actually be released...
